Separation of Clean and Dirty Spaces

Shoes specifically for use in the male toilet room (the rest of the building, a mountain lodge is a shoe free environment) the result of a strong separation between clean and dirty. Visually the strongest demarkation of boundaries is the presence of the objects, toilet slippers, themselves.

Does it, should it, or could it apply to the storage and separation of clean and dirty (or private and not so private) digital content? Beyond the obvious, what makes for dirty content?
